What Is The Value Of X?

Answers

Answer 1

Answer:

x = +5

Step-by-step explanation:

The triangles ADB and BDC are similar.  Thus it is possible to write an equation of ratios and solve it for x:

 x       10

----- = -------

10       4x

Cross-multipying, we get:

4x^2 = 100, which yields x = +5

Identifying the slope, y-intercept and x- intercept of each

Answers

Answer:

slope= -3

y-intercept= 6

Step-by-step explanation:

1. Approach

To solve this problem, one needs the slope and the y-intercept. First, one will solve for the slope, using the given points, then input it into the equation of a line in slope-intercept form. The one can solve for the y-intercept.

2.Solve for the slope

The formula to find the slope of a line is;

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where (m) is the variable used to represent the slope.

Use the first two given points, and solve;

(1, 3), (2, 0)

Substitute in,

[tex]\frac{(0)-(3)}{(2)-(1)}[/tex]

Simplify;

[tex]\frac{-3}{1}\\\\=-3[/tex]

3. Put equation into slope-intercept form

The equation of a line in slope-intercept form is;

[tex]y = mx + b[/tex]

Where (m) is the slope, and (b) is the y-intercept.

Since one solved for the slope, substitute that in, then substitute in another point, and solve for the parameter (b).

[tex]y=-3x+b[/tex]

Substitute in point (3, -3)

[tex]-3=-3(3)+b\\-3 = -9 + b\\6 = b[/tex]

What is the slope of the line that passes through the points (-2,7) and (2, -5)?
Write your answer in simplest form.

Answers

Answer:

m=-3

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

Slope = Rise/Run

We can find the amount between 7 and -5 as 12, and -2 and 2 as 4.

Then we can do rise/run and 12/4

Which would divide into 3.

ANd because we can see the x increases as the y decreases, we can find that it's a negative slope.

x=4y-1
x+2y=11

Answers

Answer:

x = 7, y = 2

Step-by-step explanation:

x= 4y -1

since x is by itself 4y-1 will substitute for x in the other equation x+2y=11

it will become 4y-1+2y=11

+1 +1

add one to both sides since is doesn't have a variable.

it will become 4y+2y= 12 now add 4y+2y

becomes 6y=12

_ _

6 6

divide by 6 on each side and you get y=2.

now x=4(2)-1 you will substitute y into the first equation.

Line m passes through points (3, 15) and (10, 9). Line n passes through points (2, 9) and (9, 3). Are line m and line n parallel or perpendicular?

Answers

Answer:

The two lines 'm' and 'n' are parallel

Step-by-step explanation:

Explanation

Given that the line 'm' points (3,15) and (10,9)

The slope of the line 'm'

                = [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1} } = \frac{9-15}{10-3} = \frac{-6}{7}[/tex]

Given that the line 'n' points (2,9) and (9,3)

The slope of the line 'n'

             = [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1} } = \frac{3-9}{9-2} = \frac{-6}{7}[/tex]

The slope of line 'm' = The slope of  line 'n'

Both slopes of the lines are equal

∴ The two lines are parallel

Choose the two expressions that are equivalent to 5. 75 ÷ 1. 15
A: 575 ÷115
B: 5,750 ÷ 1,150
C: 5,750 ÷ 115
D: 575 ÷ 1,150​

Answers

Answer:

A and B, but I’m gonna explain it the best I can too.

Step-by-step explanation:

5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.

Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.

This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression

they have to add up completely the same.
